[0042] A mist-free humidifier is a new type of humidifier that humidifies the environment by blowing water from a wet curtain into the surrounding air. The humidifier uses a water pump to draw water from the tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the tank at the bottom, and the pump circulates the water through the wet curtain. Existing wet curtains are generally made of absorbent cotton, fabric, or paperboard, which have the following problems: they are prone to cracking after prolonged soaking; bacteria can easily grow inside the wet curtain, and with the fan blowing, bacteria can easily disperse into the air along with the moisture, potentially affecting the user's health if inhaled; wet curtains need to be replaced, resulting in high production and maintenance costs and a relatively complex manufacturing process.

[0043] Wet curtains that use rigid materials such as plastic as the base material instead of traditional spunlace fabric can reduce problems such as bacterial growth, and users can clean them themselves without replacing them during use. However, this type of mechanism also has certain drawbacks: uneven water distribution on the surface of the curtain core and the non-absorbent nature of the base material can both lead to poor humidification effects.

[0044] In view of this, the present invention improves the structure of the wet curtain composed of hydrophobic material substrate, and provides a wet curtain assembly that can increase the uniform water distribution effect and improve the humidification effect.

[0045] Please refer to Figures 1 to 3 The wet curtain assembly 100 includes multiple curtain cores 1 stacked vertically. The curtain cores 1 are made of water-resistant material. The middle of the multiple curtain cores 1 together forms an air passage extending vertically. Multiple air inlet channels are formed between two adjacent curtain cores 1 and connected by the air passage 13. A water storage tank 111 extending circumferentially along the upper end surface of each curtain core 1 is formed. Multiple water outlets 112 are provided on the inner wall of the water storage tank 111 at intervals along its circumferential direction, so that the water in the water storage tank 111 fills the bottom 111 of the water storage tank 111 circumferentially and then flows out through the multiple water outlets.

[0046] In the technical solution of this utility model, when the water in the lower water tank 300 is guided to each wet curtain structure, it needs to be filled around the bottom of the water storage tank 111 before it can flow out from multiple water outlets 112. This means that a certain amount of water needs to be stored in the water storage tank 111 before the water distribution action is carried out, ensuring that water can pass through each water outlet 112, thereby ensuring the uniformity of water distribution during the flow and diffusion of water between two adjacent curtain cores 1.

[0047] In this invention, the material of the curtain core 1 is a water-resistant material. This material can be repeatedly washed and maintains its physical / chemical stability under conditions such as soaking, rubbing, and washing. Combined with its water resistance, wear resistance, and chemical resistance, the material has a longer lifespan, allowing the wet curtain to achieve a consumable-free effect throughout its service life. It can be made of plastic or other rigid materials, and each curtain core 1 can be removed for rinsing and cleaning.

[0048] Furthermore, the material of the curtain core 1 is a hydrophobic material, specifically it can be made of rigid materials such as plastic or metal, so that the curtain core 1 can be removed for rinsing and cleaning.

[0049] The specific number of curtain cores 1 is not limited and can be reasonably set according to the design height and humidification effect of the humidifier 1000.

[0050] This utility model does not limit the specific shape of the curtain core 1, which can be a block structure, a sheet structure, etc. In this embodiment, in order to increase the air volume, the curtain core 1 is arranged in a ring shape, the water storage tank 111 is set as a ring groove, and multiple water inlets 112 are arranged at intervals along the circumference of the curtain core body 11.

[0051] Furthermore, the width of the water storage tank 111 gradually decreases from top to bottom. That is, the water storage tank 111 has a structure that is low in the middle and high on both sides. This is conducive to storing a certain amount of water in the water storage tank 111 and ensuring diffusion efficiency. It should be noted that the cross-sectional shape of the water storage tank 111 is not limited and can be V-shaped, U-shaped, etc.

[0052] Based on the above embodiments, please refer to Figure 6 The water storage tank 111 has two opposite sidewalls extending from bottom to top in a direction away from each other in its width direction, with an included angle α between the two sidewalls, where 120°≤α<180°. This angle range gives each sidewall a certain slope, thus providing a good flow guiding effect. Preferably, α is set to 160°, which not only ensures the effective water accumulation volume of the water storage tank 111, but also allows the water storage tank 111 to form a large water storage surface.

[0053] Based on the above embodiment, the water storage tank 111 has a plurality of water outlets 112 on its side wall in the width direction. In this structure, after the water in the water storage tank 111 is filled with water in one circle, it will not flow out until the water level of the entire circle reaches the height of the water outlets 112.

[0054] In other embodiments, the bottom wall of the water storage tank 111 is provided with a plurality of water outlets 112, and the periphery of each water outlet 112 protrudes upward. In this structure, the upper edge of the water outlet 112 is set above the bottom wall of the water storage tank 111, that is, the water outlet 112 is set on the protrusion, and water will only flow out after the water storage tank 111 is filled to a certain extent and the water level is higher than the protrusion. In this embodiment, the water storage tank can be a conventional tank with a certain depth, such as a U-shaped tank, or it can be a tank whose width gradually decreases from top to bottom, such as a V-shaped tank.

[0055] In some embodiments, please refer to Figures 2 to 3 The multiple curtain cores 1 include a first curtain core 11a and a second curtain core 11b arranged adjacent to each other. The multiple water inlets 112 on the first curtain core 11a and the multiple water inlets 112 on the second curtain core 11b are staggered in the horizontal direction. This prevents water droplets from the upper curtain core from falling directly out of the lower curtain core 1. By staggering the water inlets 112 of the first curtain core 11a and the second curtain core 11b, the water discharged from the water inlets 112 of the first curtain core 11a can drip onto the side wall of the water storage tank 111 of the second curtain core 11b, and needs to collect around the bottom of the water storage tank of the second curtain core 11b before flowing out. This helps to increase the water adhesion area and prevents the water from flowing away before it has fully diffused on the curtain core 1.

[0056] It should be noted that the first curtain core 11a and the second curtain core 11b can be part of multiple curtain cores 1, or multiple curtain cores 1 can be set as multiple first curtain cores 11a and multiple second curtain cores 11b, with multiple first curtain cores 11a and multiple second curtain cores 11b alternately arranged, thereby dividing the curtain core 1 into two different curtain core forms.

[0057] It should be understood that the structures of the water storage tanks 111 in the first curtain core 11a and the second curtain core 11b can be the same or different. In some embodiments, the water storage tanks in the first curtain core 11a and the second curtain core 11b are both V-shaped grooves. In this case, the water inlets 112 of the first curtain core 11a and the second curtain core 11b can be located on the same sidewall of the water storage tank 111, and can be staggered in the circumferential direction or in the width direction of the water storage tank 111. The water inlets 112 of the first curtain core 11a and the second curtain core 11b can also be located on the sidewalls of the water storage tank 111 in different directions, thus naturally forming a positional offset. For example, the water storage tanks 111 in the first curtain core 11a and the second curtain core 11b are both V-shaped grooves with opposing first and second sidewalls. The first sidewall of the water storage tank 111 in the first curtain core 11a is provided with multiple water inlets 112, and the second sidewall of the water storage tank 111 in the second curtain core 11b is provided with multiple water inlets 112. This can achieve the effect of uniform water distribution and ensure the water distribution area.

[0058] In other embodiments, the water storage tank 111 of the first curtain core 11a is a V-shaped groove, and a water outlet 112 is provided on the side wall of the water storage tank 111 accordingly. The water storage tank 111 of the second curtain core 11b is a U-shaped groove, and a water outlet 112 with an upward protruding periphery is provided on the bottom wall of the water storage tank 111 accordingly.

[0059] Please refer to Figures 4 to 5 The first curtain core 11a has multiple water outlets 112 on its two opposite side walls in the width direction of its water storage tank 111. In this case, the water in the water storage tank 111 first fills the entire circumference and reaches a certain height before overflowing from the corresponding water outlet 112, which is beneficial for water storage in the water storage tank 111. The second curtain core 11b has multiple water outlets 112 on the bottom wall of its water storage tank 111, and the periphery of each water outlet 112 protrudes upwards. Thus, even if the water flows directly to the bottom of the water storage tank 111, the protruding periphery of the water outlet 112 effectively creates a boss-like hole at the bottom of the water storage tank 111, requiring the water in the water storage tank 111 to accumulate to a certain height before overflowing, which is beneficial for water storage and diffusion in the water storage tank 111. In this embodiment, the upper and lower water inlets 112 are distributed in the width direction. After the water from the first curtain core 11a is guided, it falls on the side wall of the water storage tank 111 of the second curtain core 11b. After diffusion and collection, it can be discharged from the water inlet 112 of the second curtain core 11b, which increases the uniformity of water distribution and improves the amount of water adhering.

[0060] It should be understood that when the water storage tank 111 of the second curtain core 11b is arranged in a V-shape, the water outlet 112 is correspondingly arranged at the connection of the two side walls of the water storage tank 111.

[0061] It should be noted that the diameters of the water inlets 112 of the first curtain core 11a and the second curtain core 11b can be the same or different. Considering the water flow rate, in this embodiment, the aperture range of the water inlet 112 is 3mm to 8mm, thereby ensuring that the water can flow smoothly to the next layer without the water accumulation rate in the water storage tank 111 being much greater than the water storage rate, causing the water in the water storage tank 111 to overflow from the port of the water storage tank 111. Preferably, the aperture of the water inlet 112 is set to 5mm. This achieves a good water flow effect without affecting the water storage volume of the water storage tank 111.

[0062] For a single curtain core 1, the area of ​​the water inlet 112 will affect the diffusion speed and diffusion range of the water flow. Therefore, the area occupied by multiple water inlets 112 should be adjusted by considering the number and quality of the water inlets 112.

[0063] Furthermore, the evaporative cooling pad assembly includes multiple water distribution structures 12 disposed within multiple air inlet channels. Each water distribution structure 12 extends along the width of the air inlet channel. When the cross-sectional area of ​​the air inlet channel is circular, it extends radially. The upper end of each water distribution structure 12 is connected to the corresponding curtain core 1 and corresponds to multiple water outlets 112, while the lower end has a gap with the corresponding curtain core 1. The water distribution structure 12 is located below the corresponding curtain core 1. At this time, the water discharged from the water outlet 112 of the upper curtain core 1 is guided by the water distribution structure 12 connected to the curtain core 1 and drips into the water storage tank 111 for collection. The water distribution structure 12 plays a guiding role, allowing the water flow to diffuse between adjacent curtain cores 1.

[0064] It should be understood that if the water distribution structure 12 comes into contact with the lower curtain core 1, it will affect the water distribution effect of the water filling the entire circle before the water is discharged. Therefore, through the gap fit between the water distribution structure 12 and the lower curtain core 1, the external air enters the air passage through the gap of the water distribution structure and the gap between the water distribution structure and the corresponding curtain core 1, and then is guided to the fan assembly 400 and discharged.

[0065] This utility model does not limit the specific form of the water-dividing structure 12. The water-dividing structure 12 should have a certain water-hanging area and a flow-guiding function. In this embodiment, the water-dividing structure 12 includes multiple water-dividing components arranged at intervals along the circumference of the air passage. Each water-dividing component includes two water-dividing plates 121 spaced apart along the width direction of the air passage. That is, the multiple water-dividing plates 121 are arranged along the circumference of the curtain core 1 and form a two-ring arrangement. There is a certain interval between the two water-dividing plates 121 in each water-dividing component, so as to facilitate the flow and diffusion of water between the multiple curtain cores 1.

[0066] In some embodiments, the sum of the cross-sectional areas of the plurality of water inlets 112 of the first curtain core 11a is s1, and the upper surface area of ​​the first curtain core 11a is S1, wherein s1 / S1≤0.3. In some embodiments, the sum of the cross-sectional areas of the plurality of water inlets 112 of the second curtain core 11b is s2, and the upper surface area of ​​the first curtain core 11a is S2, wherein s2 / S2≤0.1. Preferably, the ratio of s1 to S1 in the first curtain core 11a is set to 0.2, and the ratio of s2 to S2 in the second curtain core 11b is set to 0.02, thereby controlling the flow rate and diffusion range of water in the first curtain core 11a and the second curtain core 11b. That is, the density of the water inlets on the first curtain core 11a and the second curtain core 11b is different when the sizes are the same, and the number of water inlets 112 in the first curtain core 11a is greater than the number of water inlets 112 in the second curtain core 11b. For the first curtain core 11a, the water inlets 112 are located on the side wall of the water storage tank 111. The number of water inlets 112 is limited only by the circumferential dimension of the water storage tank. Therefore, the spacing between two circumferentially adjacent water inlets 112 can be smaller and their number can be denser, thus allowing for the installation of more water distribution components and increasing the wetting area. The water inlets 112 of the second curtain core 11b are located at the bottom and are convex around the periphery. This protruding hole structure itself creates some resistance to the flow of water in the water storage tank 111. Therefore, considering water distribution, it is necessary to avoid the protruding holes being too dense and affecting water flow. Thus, the water inlets 112 on the second curtain core 11b need to be relatively sparse.

[0067] Please refer to Figure 4 and Figure 6 The water storage tank 111 of the first curtain core 11a has multiple water inlets 112 on its two opposite side walls in the width direction. Two water dividers 121 in each water divider correspond to the two opposite water inlets 112 in the width direction of the water storage tank 111. In this structure, the water flowing out of each water inlet 112 can fall onto the corresponding water divider 121, thus being guided by the water divider 121. That is, the downward projection of each water inlet 112 can fall onto the corresponding water divider 121.

[0068] It should be understood that when the side wall of the water storage tank 111 is inclined, the water divider 121 is also inclined, and the inclination is consistent with the side wall of the water storage tank 111. At this time, the straight lines of the two water dividers 121 in each water divider are set at an angle.

[0069] It should be noted that the upper end of the water divider 121 is provided with a protrusion so that it can be directly opposite the water inlet 112. The protrusion can extend into the water inlet 112 to ensure the water guiding effect. The water divider 121 can also form a gap with the water inlet 112 to avoid affecting the outflow of water.

[0070] Please refer to Figure 5 The bottom wall of the water storage tank 111 of the second curtain core 11b is provided with multiple water inlets 112. The water distribution structure 12 also includes multiple guide ribs 122 located at the lower end of the curtain core body 11 of the second curtain core 11b. Each guide rib 122 is located between the corresponding water inlet 112 and the water distribution component, and can contact the upper surface of the two water distribution plates 121 in the corresponding water distribution component. In this structure, the downward projection of each water inlet 112 falls on at least the guide rib 122. When the aperture of the water inlet 112 is larger than the interval between the two water distribution plates 121 in each water distribution component, the downward projection of the water inlet 112 falls on the two water distribution plates 121 and the guide rib 122. Since the water outlet 112 of the second curtain core 11b is located on the bottom wall of the water storage tank 111, in order to prevent the water discharged from the second curtain core 11b from flowing directly between the two water dividers 121, it is connected by a guide rib 122 to fill the gap between the two water dividers 121. The water in the water outlet 112 first falls on the guide rib 122 and is diverted to the two water dividers 121 along the length of the guide rib 122, thereby achieving the diversion effect.

[0071] It should be noted that the guide rib 122 is located at the lower end of the water outlet 112, and can be fixed on the curtain core body 11 or connected to the water divider 121.

[0072] In this embodiment, the ends of the two water-dividing plates 121 in each water-dividing component that are away from each other are connected to the corresponding curtain core body 11, and each curtain core 1 is integrally formed.

[0073] To ensure even water distribution, a water distribution box 2 is provided above each of the multiple curtain cores 1. The water distribution box 2 is used to connect to the water source, and multiple water outlets 21 are opened at the lower end of the water distribution box 2. The downward projection of the multiple water outlets 21 falls into the water storage tank 111. It should be understood that the water distribution box 2 can hold a certain volume of water. The structural form of the water distribution box 2 is not limited; it can be a trough-shaped structure with an open upper end, or a closed structure composed of a bottom box and a top cover.

[0074] Furthermore, the evaporative cooling pad assembly 100 may include a bracket 3, which has a frame structure. The bracket 3 includes an annular base plate and multiple supporting ribs. The annular base plate has multiple through holes to facilitate water flow. The annular base plate can provide support and positioning for multiple curtain cores 1. The multiple supporting ribs are located on the periphery of the annular base plate and correspond to the outer walls of the multiple curtain cores 1, thereby restricting the position of the multiple curtain cores 1. The water distribution box 2 is fastened to the upper side of the bracket 3.

[0075] It should be understood that the gap between two adjacent curtain cores 1 can be guaranteed by setting a corresponding limiting structure on the inner or outer side of each curtain core 1, or by setting a blocking structure on the support rib of the bracket 3.

[0076] In this invention, the wet curtain assembly 100 is made of plastic. Each curtain core 1 can be removed for rinsing and cleaning. By setting a water storage tank 111 on each curtain core 1, and making the height of the two sides of the water storage tank 111 greater than that in the middle, the water from the sides can quickly spread towards the middle under the action of gravity, increasing the effective surface area for water evaporation. Water needs to fill a circle at the bottom of the water storage tank 111 before it can be distributed, ensuring the uniformity of water distribution. The water outlets 112 on two adjacent curtain cores 1 are radially staggered to prevent water from falling directly into the next layer and to facilitate the water flow to fully wet the surface of the curtain core 1. At the same time, the ratio range of the aperture and area of ​​the water outlet 112 to the upper surface of the corresponding curtain core 1 is designed to achieve an optimized wetting effect. The multiple water distribution plates 121 on each curtain core 1 are set in two circles with a break in the middle, which facilitates the flow and diffusion of water between multiple curtain cores 1.

[0077] This utility model also proposes a humidifier 1000, which includes a wet curtain assembly 100. The specific structure of the wet curtain assembly 100 is as described in the above embodiments. Since the humidifier 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0078] For details, please refer to Figure 7 The humidifier 1000 also includes a housing 200, a fan assembly 400, and a water tank 300. The housing 200 has an air inlet and an air outlet, as well as a ventilation channel connecting the air inlet and the air outlet. Specifically, an air inlet is provided on the side surface of the housing 200, and an air outlet is provided on the top of the housing 200. The inner cavity of the housing 200 forms a ventilation channel. The fan assembly 400 and the evaporative cooling pad assembly 100 are both located inside the housing 200 and within the ventilation channel; and the evaporative cooling pad assembly 100 is located within the fan assembly. Below the housing 200 and within the ventilation channel, the evaporative cooling pad assembly 100 corresponds to the area where the housing has an air inlet. A water tank 300 is located inside the housing 200 and below the evaporative cooling pad assembly 100. The water tank 300 guides water through the water pipe 4 to the upper end of the evaporative cooling pad assembly 100 and collects water flowing down from the evaporative cooling pad assembly 100. The fan assembly 400 drives airflow from the air inlet, through the air inlet channel and the air passage of the evaporative cooling pad assembly 100, to the air outlet. This allows external air to enter the ventilation channel through the air inlet of the housing 200 via the gap between two adjacent cooling pads 1 and exit from the air outlet of the housing 200.

[0079] The air inlet on the housing 200 should be set to correspond to the evaporative cooling pad assembly 100, and the part of the housing 200 corresponding to the fan assembly 400 should not be provided with an air inlet. This is to avoid the air flowing directly from the fan assembly 400 without passing through the evaporative cooling pad assembly 100, which would result in ineffective humidification.

[0080] It should be understood that the water pipe 4 can be located inside or outside the wet curtain assembly 100. In one embodiment, a limiting channel is formed on the side of the wet curtain assembly 100, which passes through multiple curtain cores to position the water pipe 4.

[0081] Water in water pipe 4 is guided into water distribution box 2. By setting the inlet flow rate and the outlet flow rate of water distribution box 2, the water can be absorbed to a certain volume and cover all the water outlets 21 in water distribution box 2, thereby achieving a multi-directional uniform water distribution effect.

[0082] Furthermore, the humidifier 1000 also includes a base 500, which overlaps with and is fastened to the upper end of the water tank 300. The wet curtain assembly 100 is mounted on the upper end of the base 500, and the fan assembly 400 is mounted on the upper end of the wet curtain assembly 100 and extends to the base 500 through a connector and is fastened to the base 500, thus forming a stable structure.

[0083] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
